FIELD OF THE INVENTION

The presently disclosed embodiments relate to insufflation andirrigation conduits for vessel harvesting systems and methods of theiruse. In particular, the present disclosure relates to a system having acombined cabling for providing gases, liquids, and/or electrical powerto an attached medical device and method of use.

BACKGROUND

Generally, surgical devices, such as devices for vessel harvesting, willrequire the use of multiple tools each including dedicated wiring ortubing for each particular function. As such, the surgical area can bedisorganized and over encumbered by the various devices, wiring, andcables when performing a surgical procedure. In one example, vesselharvesting is a surgical technique that is commonly used in conjunctionwith coronary artery bypass surgery. During a bypass surgery, blood isrerouted to bypass blocked arteries to restore and improve blood flowand oxygen to the heart. The blood may be rerouted using a bypass graft,where one end of the by-pass graft is attached to a blood sourceupstream of the blocked area and the other end is attached downstream ofthe blocked area, creating a “conduit” channel or new blood flowconnection bypassing the blocked area. Commonly, a surgeon will removeor “harvest” healthy blood vessels from another part of the body tocreate the bypass graft. The success of coronary artery bypass graftsurgery may be influenced by the quality of the conduit and how it ishandled or treated during the vessel harvest and preparation steps priorto grafting.

Vessel harvesting methods involve selecting a vessel, traditionally, thegreat saphenous vein in the leg or the radial artery in the arm to beused as a bypass conduit sealing off and cutting smaller blood vesselsthat branch off the main vessel conduit and harvesting the main conduitfrom the body. This practice does not harm the remaining blood vesselnetwork, which heals and maintains sufficient blood flow to theextremities, allowing the patient to return to normal function withoutnoticeable effects.

A minimally invasive technique for vessel harvesting is known asendoscopic vessel harvesting (“EVH”), a procedure that requires onlysmall incisions. During EVH and similar surgical procedures, media areinsufflated or injected into the patient's leg cavity to expand the legcavity and provide a good visual field inside the leg cavity or flushtissue or components. The media is provided in the operating room (“OR”)and delivered via a flexible tube to the sterile field.

Some EVH devices have small lengths of tubing extending from theirbodies at the handle with which the operator (e.g., surgeon, physicianassistant) can connect this OR tube. The connection can be included onthe flexible trocar of the EVH device. In all cases, the OR tube must bepresent in the sterile field and is attached to the EVH system at ornear the handle of the device, where the operator's hands are, atop theOR table. Also, all EVH devices have a power cable to deliver energy tothe patient (see, e.g., FIG. 1). This power cable is connected to theEVH device at or near its handle, which again is atop the OR table inthe sterile field. The power cable extends approximately 10 feet or soto an OR-supplied generator, typically on a cart (outside of the sterilefield).

The foregoing arrangement for performing an EVH procedure in a typicalOR setting is illustrated in FIG. 2. In such conventional configurationsthere are many tubes, wires, and instruments that clutter the OR tableand the sterile field, thereby impeding the progress of the operator(e.g., surgeon, physician assistant). Frequently the tubing and wiresbecome entangled as the EVH device is rotated during a normal EVHprocedure. It is therefore advantageous to remove as many tubes andwires as possible from this area, to minimize the clutter in the sterilefield and simplify the EVH procedure. Such OR table and sterile fieldcluttering and the resulting entanglement and related difficulties arealso present in other types of laparoscopic and endoscopic surgicalprocedures.

DETAILED DESCRIPTION

An illustrative embodiment of the present disclosure relates to a devicecombining electrical wiring and a fluid transferring channel within asingle shielded housing for use by one or more surgical or medicaldevices. Specifically, the present disclosure relates to systems andmethods for creating and using a combined cord used for surgical ormedical devices, for example, providing power, insufflation, andirrigation conduits for an endoscopic vessel harvesting (EVH) device.Some embodiments of the present disclosure include a surgical device,for example, an EVH device. The surgical device can include a body, acable operationally engaging at least the body, and a conduit formed atleast partially within the cable. The conduit may be for insufflation orirrigation. In some embodiments, the power cabling and insufflationconduits can be combined into a single structure for providing power anddelivering media (i.e., fluids such as gases (e.g., CO₂) or liquids(e.g., saline)) during a surgical procedure while minimizing clutter inthe sterile field and on the OR table, to ultimately simplify theprocedure. In other words, the power cable of the surgical device can bedesigned to include a media delivery lumen therein using the singlecabling structure. Power can be delivered to the surgical device whilemedia can be delivered to the patient via the delivery lumen. In someembodiments, the power cable of the EVH device can be configured toinclude a space sufficient to deliver the media without the presence ofan additional delivery lumen.

In some embodiments of the present disclosure include a method fordelivering media to a body of a patient within a sterile field using thesystem of the present disclosure. The method can include steps for (a)providing a surgical device having a cable and a conduit formed at leastpartially within a single cable, the conduit having a proximal endlocated outside of the sterile field and a distal end located inside ofthe sterile field, (b) operably connecting the proximal end of theconduit to a media supply tube outside the sterile field, and (c)delivering media from the media supply lumen to the patient's body partthrough the distal end of the conduit. The method can be performedduring different types of operations, including an endoscopic vesselharvesting EVH procedure. The method can be used to deliver differentcombinations of gases and liquids to a body of the patient, for example,insufflating the patient's body part and/or irrigating the patient'sbody part.

FIGS. 1 through 5C wherein like parts are designated by like referencenumerals throughout, illustrate an example embodiment or embodiments ofimproved operation for medical devices requiring multiple wired,tubular, etc. connections, according to the present disclosure. Althoughthe present disclosure will be described with reference to the exampleembodiment or embodiments illustrated in the figures, it should beunderstood that many alternative forms can embody the presentdisclosure. One of skill in the art will additionally appreciatedifferent ways to alter the parameters of the embodiment(s) disclosed,such as the size, shape, or type of elements or materials, in a mannerstill in keeping with the spirit and scope of the present disclosure.

Referring to FIG. 1, an exemplary vessel harvesting device 100 inaccordance with the present disclosure is depicted. The device 100, insome embodiments, can include housing 102 which can be configured tohouse the various components of the device 100, including internalwiring to receive and deliver power to said components, and communicatedata to systems outside of the housing 102. The housing 102 can alsoinclude buttons, switches, etc. for controlling operation of the device100. For example, the housing 102 can include a button for powering acutting component of the device 100. The housing 102 can be constructedfrom any combination of materials utilizing any combination of systemsand methods known in the art. For example, the housing 102 can beconstructed from a biocompatible material, such as, plastic material,elastomeric material, metallic material, shape memory material,composite material or any other materials that has the desiredcharacteristics. In some embodiments, the device 100 and componentsthereof can be disposable.

In some embodiments, the housing 102 may be coupled to external wires orcabling 112 that are configured for providing power and transferringdata with the device 100 and the subsystems thereof. As would beappreciated by one skilled in the art, the cable 112 can also beconfigured to provide power to other systems known in the art, forexample, a cutting sub-system of the device 100, such as the cuttingsystems discussed with respect to U.S. Pat. Nos. 9,119,900, 9,498,246,9,814,481, and 9,943,328 and, all incorporated herein by reference. Thecable 112 can provide a combination of wiring for different power anddata cabling within a singular shield or can be a combination of wiresbraided together into a single line.

Reference is made to FIG. 2, which illustrates an operator using anexisting EVH system 200 in an EVH procedure for operation within an OR.The EVH system 200 can include an EVH device 100 having a power cable112 attached thereto. The EVH system 200 can also include multiple othertubes and wires, including a clear tube 122 that terminates/forms aconnection at a trocar portion 124 of the EVH device 100. The clear tube122 is the media delivery tube provided by the OR. In some embodimentsof the disclosed device and method (as discussed below), the EVH systemis modified such that the media delivery tube 122 is integrated into thepower cable 112, whereby the media connection is formed at thegenerator, 5-10 feet away (not shown) instead of at the trocar portion124, as shown in FIG. 2. The media delivery tube 16 is thereby beremoved from the sterile field, reducing clutter in the sterile fieldand on the OR table, and simplifying the EVH procedure.

Continuing with reference to FIGS. 1 and 2, in some embodiments, thedevice 100 can include an elongated body 104 that can be configured forpassing extravascular through an entry incision to a vessel harvestingsite and configured to introduce media from one or more tubes 122 to theincision site. To aid in navigating the elongated body 104 to a site ofharvesting, the elongated body 104 may be sufficiently rigid axiallyalong its length. To provide the elongated body 104 with suchcharacteristic, in an embodiment, the elongated body 104 may be madefrom a biocompatible material, such as, plastic material, elastomericmaterial, metallic material, shape memory material, composite materialor any other materials that has the desired characteristics. To theextent desired, the elongated body 104 may be provided with someflexibility to move radially or laterally from side to side depending onthe application.

In some embodiments, an elongated body 104 can extend longitudinallyfrom the distal end of the housing 102. The elongated body 104 can besubstantially solid or hollow and have a proximal end 106 and a distalend 108. The proximal end 106 can be coupled to and/or within thehousing 102 using any combination of coupling mechanisms. In someembodiments, the elongated body 104 can include an inner cavityextending from the proximal end 106 to the distal end 108 to enabletransmission of media from the canister trocar portion 124 or otherconnection point. As would be appreciated by one skilled in the art, theelongated body 104 can house and/or be coupled to a variety of othertools or components, for example, a cutting tool.

In some embodiments, the device 100 may include one or more lumen withlumen that accommodate advancing instruments, wires, or materialstherethrough. In some embodiments, the device 100 may include a conduitthrough which wires or cabling may be advanced for powering and/orcommunicating with electrical components within the device 100.Similarly, the device 100 can include a conduit for transmission ofmedia from the trocar portion 124 or other connection point to a desireddestination. The conduit for transmission of the media can be sharedwith the other components or can be an isolated separate conduit exitingout the tip 120 of the device 100.

In some embodiments, elongated body 104 can terminate at a dissectiontip 120 or can have a dissection tip 120 coupled to the distal end 108of the elongated body 104. In some embodiments, the dissection tip 120may include a generally tapered section which terminates in a generallyblunt end for atraumatic separation of a vessel segment, being harvestedfrom surrounding tissue, while minimizing or preventing tearing orpuncturing of nearby vessels or tissue as the device 100 is navigatedalong a vessel segment. Although illustrated as being blunt, it shouldof course be understood that, to the extent desired, the end of thedissection tip 120 may be made relatively pointed to enhance advancementof the distal end of the device 100. Similarly, the tapered section maybe configured differently structurally, so as to enhance the operabilityof the device 100.

In some embodiments, to reduce likelihood of trauma during a dissectionprocess, in some embodiments, the dissection tip 120 may be radiallypliable, flexible or deformable so that the dissection tip may deflectslightly under exertion of force applied to the dissection tip 120. Insome embodiments, the dissection tip 120 is radially compressible sothat the walls of the dissection tip 120 can deform under exertion offorce normal to the tip surface. To that end, the dissection tip 120 maybe formed from thin wall plastic material to enable the dissection tipto flex under load. Suitable materials include, but are not limited to,polycarbonate, polyethylene terephthalate glycol-modified (PETG),polyethylene terephthalate (PET) and other materials that provide enoughoptical clarity while allowing the dissection tip to flex under load. Atthe same time, the dissection tip 120 may be provided with sufficientcolumn strength in the axial or longitudinal direction to allowdissection of the vessel from the surrounding connective tissue. Othercharacteristics of the dissection tip 120 are contemplated, such ashaving variable strengths: (1) in an axial direction versus alongitudinal direction, wherein the axial strength is greater than thelongitudinal strength; (2) in a longitudinal direction versus an axialdirection, wherein the longitudinal strength is greater than the axialstrength; or (3) the axial direction versus a longitudinal direction,wherein the axial strength is approximate the longitudinal strength. Itis also possible that the dissection tip 120 may include two or morematerials, wherein at least one material can have different materialproperties, such as elasticity, hardness, tensile strength.

In some embodiments, the EVH device 100 of the present disclosure can beused to provide a gas/fluid media independent from a remote tank(s)and/or using external tubing 122 during a procedure. For example, theEVH device 100 of the present disclosure can be used to provide CO₂ fromcanisters during a vessel harvesting procedure. When using the EVHdevice 100 during an operation, the user would first make an incision ata desired location as normal. The user can also implement a tip searchor cut down method if desirable. In some embodiments, the user canutilize sealing device 200, such as a gas pad, to create a seal betweenthe patient and the EVH device 100. For example, a user can use a gasseal pad such as the gas seal pad discussed in U.S. patent applicationSer. No. 16/225,049, incorporated herein by reference. With theelongated body 104 and/or gas pad in place and insufflation is ready tobegin, the user can engage the release of the media from thecanister(s), via the tubes 122. For example, the media can be releasedunder pressure by activating a mechanism/button on the housing 102. Atthis point the internal canister(s) will release the stored media (e.g.,CO₂) into the patient. A mechanism internal to the EVH device 100 cancontrol the pressure and flow rate of the media delivered from thecanister. If the user would like to remove the EVH device 100 orotherwise stop flow/pressure, the user can disengage the release orpressure through the same mechanism/button on the handle.

Referring to FIG. 3, in some embodiments, a system 300 is provided todeliver power, signals, gas, liquid, and/or lighting through a singlecombined cabling structure 310. FIG. 3 illustrates a cabling 310 fordelivering a combination of power, signals, gases, liquids, and/orlighting to a medical device, for example, the EVH device 100. Thecabling 310 can be designed to safely encase a combination of wiring,lumens, and conduits for the power, signals, gases, liquids and/orlighting to be delivered over a single line instead of having multiplecables with separate cables for each utility (e.g., power, signals,insufflation, lighting, etc.), such as depicted in FIG. 2. The cabling310 can be sized and shaped to encase all the wiring and conduits whilealso remaining flexible for ease of movement by an operator.

In some embodiments, the cabling 310 can include or otherwise house anelectrical wiring 312 for conveying a combination of power from a powersource (not shown), signals to/from a processing unit or othercircuitry, and a media delivery lumen 314 for conveying a media (e.g.,CO₂, flushing, etc.) from a medium container or reservoir (not shown).The electrical wiring 312 can include any combination of wire types,made from any combination of conductive materials, in any range ofgauges, etc. In some embodiments, the cabling 310 can include abifurcation 316 junction where the media delivery lumen 314 and theelectrical wiring 312 separate for attachment to their respective sourcedevices. The cabling 310 can further include a distal end 318 oppositethe bifurcation 316 with a length of the cabling 310 a (e.g., a flexibleelongated body) extending therebetween. The distal end 318 can includethe wiring and conduit connectors needed to be coupled to a medicaldevice (e.g., EVH device 100) secured within the EVH device (not shown).

Referring to FIG. 4A, an example view of the proximal end 320 of thecabling 310 is depicted. The proximal end 320 of the power cable can belocated at an opposing end of the cabling 310 from the device 100attached thereto (i.e., the generator end, or proximal end). In someembodiments, the proximal end 310 can include the bifurcation 316, anelectrical plug 322, and a lumen connection 324 for coupling torespective power sources and gas/liquid sources. The electrical plug 322and the lumen connection 324 can include any combination of couplingmechanism typically found in an operating room. For example, theelectrical plug 322 can be a three prong plug and the lumen connection324 can be a Luer connector.

In some embodiments, the electrical wiring 312 can be coupled to theelectrical plug 322 and can extend to and/or is coupled to thebifurcation 316. Similarly, the lumen 314 can be coupled to a lumenconnection 324 and can extend to and/or is coupled to the bifurcation316. The bifurcation 316 is the junction point for the separate wiring312 and the lumen 314 combining to form a single cabling along thelength of cabling 310 a. In some embodiments, the bifurcation 316 can bedesigned to be located proximate an OR generator, which is typically5-10 feet away from the sterile field/OR table, where the OR mediasupply lumen would connect (i.e., away from the sterile field). In sucha configuration, an operator (e.g., surgeon, physician assistant) canmake the media connection via the lumen connection 324 from the ORsupply and a power connection via the electrical plug 322 at thegenerator, outside of the sterile field (e.g., about 5-10 feet away). Inother words, the bifurcation 316 provides a y-type connection combiningthe electrical wiring 312 and the lumen 314 into the single length ofcabling 310 a for use within a sterile field and extending to themedical device 100.

Referring to FIG. 4B, an example view of the distal end 318 of thecabling 310 is depicted. The distal end 118 of the power cable can belocated at the end of the cabling 310 that is coupled to the medicaldevice 100. In some embodiments, the distal end 318 can include the endof the length of cabling 310 a and can include a molded strain relief326 coupled to the distal end of the length of cabling 310 a. The moldedstrain relief 326 can be designed to provide a sealed connection betweenthe end of the length of cabling 310 a and an opening within a housingof the device 100. The molded strain relief 326 can also provide theflexibility for the device 100 and the cabling 310 to move freelywithout risk of damaging the coupling point of the two.

In some embodiments, the electrical wiring 312 and the lumen 314 canextend beyond the length of cabling 310 a and the molded strain relief326 to be connected to their respective termination points within thehousing of the device 100. For example, the electrical wiring 312 can beconnected to the electrical system of the device 100 and the lumen 314can be connected to the dispersion mechanism of the device 100. In otherwords, the electrical wiring 312 and the lumen 314 can exit the cabling310 to the inside the body of the device 100, with its terminationpoints hidden from view of the user. With the ends of the electricalwiring 312 and lumens 314 located within the device body, they can becoupled to various components of the device for their respective uses.For example, the electrical wiring 312 can be directly soldered to theirleads, tab connectors, circuit boards, etc. to provide a combination ofpower and signals for use by the attached device. In some embodiments,the lumen 314 can exit the cabling 310 to a position within of the bodyof the device 100. Regardless of the configuration, the appropriateconnections of the electrical wiring 312 and the lumen 314 can be madeby the device manufacturer (i.e., during fabrication of the device), andnot by the operator of the device (e.g., the surgeon, physicianassistant).

In some embodiments, the electrical wiring 312 can include multipleelectrical wires with various electrical connectors. In one example, theelectrical wiring 312 can include three wires including a hot wire, aneutral wire, and a ground wire. Each of the wires can be coupled to theappropriate termination points within the device 100. For example,referring to FIG. 4B, one wire can be connected to ground, one to power,and at least two wires can be connected to an activation switch for thedevice 100. In some embodiments, the lumen 314 can feed into the body ofthe device 100 and can be designed to provide the device 100 with gasand/or liquid for delivery from the device. For example, the lumen 314can be used by a EVH device to provide insufflation. In someembodiments, the lumen 314 can include a filter at a distal end openingof the lumen 314, to block particulate matter in the media frominadvertently being delivered to the patient, potentially causingserious injury or death.

Referring to FIGS. 5A-5C, example cross-sectional views of the cabling310 are depicted. In some embodiments, the cabling 310 can include acable shielding 330 surrounding each of the components (e.g., the wiring312 and the lumen 314) encased within the cabling 310. The cableshielding 330 can be designed to protect the inner components whileremaining flexible. In some embodiments, the cable shielding 330 isshrink wrapped around the inner components for a tight-fittingstructure, as depicted in FIG. 5A. In some embodiments, the cabling 310can be constructed from a biocompatible material, such as, plasticmaterial, elastomeric material, metallic material, shape memorymaterial, composite material or any other materials that has the desiredcharacteristics.

In some embodiments, the electrical wiring 312 made up of a combinationof separate wires 332. The wires 332 can include any combination ofpower and/or signal transferring wires. The wires 332, as depicted inFIG. 5A, are wrapped within the cable shielding 330. The wires 332 caninclude any combination of bare conductive materials, insulatedconductive materials, and shields conductive materials. In someembodiments, the wires 332 can be 24 AWG copper wires, each insulatedwith non-phthalate PVC with the size of the wires 332 and the insulationrated for 600V.

In some embodiments, the cabling 310 can include a conduit 334 forprotecting the lumen 314 and to deliver a combination of gases andliquids to the device 100. The conduit 334 can be made from anycombination of materials, for example an insulating material. The lumen314 can be jacketed by a think paper to allow for flexibility of thecabling 310 without binding, and then wrapped again in a PVC orpolyolefin jacket. Although only a single lumen 314 is depicted in FIG.5A, any number of lumens can be used without departing from the scope ofthe present disclosure. In some embodiments, the conduit 334 can includeone opening at a distal end thereof (i.e., from which the media isejected/injected into the patient's body). In other embodiments, theconduit 334 include two or more openings at the distal end. The conduit334 can be constructed from any combination of materials at desiredlevels of flexibility/rigidity. For example, the conduit 334 can beconstructed from biocompatible materials (e.g., PVC, polyurethane,Tygon®, etc.). The conduit 334 or other surrounding for the lumens 314can be sized at a dimension that is large enough to achieve the desiredflow rates for the particular media being transferred therein, forexample, the ID can be 1/32″-¼″ ID. Similarly, the wall thickness of theconduit 334 or surrounding for a lumen 314 can depend on pressurerequirements, for example, ranging from 1/32- 1/16 mm.

In some embodiments, the cabling 310 can be unshielded when there arenot signal wires within the cabling 310, such as camera, imaging, datacables, etc. In contrast, the cabling 310 can be shielded if one or moreof the wires 332 are designed to transmit a signal. The finished cabling310, including a combination of wires 332 and lumens 314, can range insize depending on the respective sizes of the wires 332 and lumens 314included therein. For example, when designed for use with a medicaldevice (e.g., EVH device 100) the cabling 310 can be can be about 4 mmto 10 mm in diameter.

In some embodiments, the wires 332 can be spaced around a shielding 330such that the shielding 330 forms a substantially circular crosssection. In embodiments, to create a substantially circular crosssection, spaces remaining between the conduit 334 and the wires 332 canbe supplemented by spacers 336. Although the elements in FIG. 5A aresubstantially circular, any combination of shapes can be used withoutdeparting from the scope of the present invention.

Referring to FIG. 5B, in some embodiments, instead of integrating aconduit 334 within the cabling 310, the negative space between theshielding 330 and any wires 332 within the shielding 330 can constitutea pathway/cavity/space that is formed along the length of the cabling310 to create a pathway 340 for the passage of the media along thelength of the cabling 310 to the device 100. In some embodiments, thispathway 340 can be formed, for example, during the extrusion of thecabling 310. The shielding 330 (and components therein) can beconstructed from any combination of materials with different rigiditylevels, which can be selected based on desired form and function of theshielding 330. For example, the shielding 330 can be designed such thatit maintains flexibly without kinking of the wiring 312, pathway 340,and/or media conduit 334 residing therein.

Referring to FIG. 5C, in some embodiments, the cabling 310 can includeany combination of wires 332, conduits 334, etc. therein. For example,the cabling 310 can camera cables, light (e.g., fiber optic) cables,etc. Similarly, the cabling 310 can be designed for any combination offunctions and provide certain utility to the attached device. Forexample, when designed for use with the EVH device 100, the cabling 310can include a power cable for cautery, an insufflation lumen, anirrigation lumen (optional), camera power and signal cord wires, andscope light source wires or fiber optics. The cabling 310 of the presentdisclosure can incorporate any or all of those lines into a singlecabling for ease of use and reduction of clutter for an operator. Thecomponents included within the cabling 310 can vary based on the devicethat the cabling 310 is designed to operate with. This is an improvementover conventional systems in which each function has its own separatecable and/or tube. For example, a separate power cord to deliverelectricity, a separate insufflation tube to deliver media, a separatesaline tube to deliver irrigation fluid, a separate light cable todeliver light to the scope, etc.

Referring to FIG. 5D, in some embodiments, the cabling 310 can includeany combination of additional layers surrounding the wires 332 andlumens 314. For example, the wires 332 can be bundles together andsurrounded by a paper tape layer 342 and a jacket layer 344.

In operation, an operator introduces the components of the system 300into the sterile field within the OR, including the device 100 and theelectrical wiring 312 and the lumen 314 included within the singlecabling 310 structure. The operator can insert the connection points322, 324 at the proximal end 320 of the cabling 310 into the appropriatedevices. For example, the electrical plug 322 can be inserted into anelectrical outlet (i.e., away from the sterile field/OR table), and thelumen connection 324 (e.g., insufflation conduit) can be connected tothe OR media supply lumen (i.e., away from the sterile field/OR table).The operator can then initiate the desired procedure using the device100. Upon activation of the device, the media can travel through thelumen 314, which is hidden from view (i.e., in the sterile field) andburied inside the cabling 310, to deliver media to the device 100without requiring the operator to make any additional connections in thesterile field. This provides a cleaner, more elegant OR system 300,while maintaining the media delivery lumen. For example, the procedurecan be an EVH procedure using an EVH device which can use aninsufflation conduit (e.g., the lumen 314) to insufflate the leg (orother body part) of a patient as required while powering the device(e.g., the wiring 312).

In some embodiments, the length of cabling 310 a can be substantiallyuniform in shape such that there are no points where either theelectrical wires or the lumens change in materials or size. With thisdesign the length of cabling 310 a can be manufactured in continuouslengths and then cut to length. Thereafter, the end connectors (e.g.,bifurcation 316 and strain relief 326) can be affixed to each end.

Although the present disclosure provides an example for using thecabling system 100 with an EVH device, the cabling system 100 of thepresent disclosure can be used with any combination of surgical ormedical devices as well as non-surgical devices. In other words, thecabling can be used with any combination of devices that require one ormore cables or lines attached to various machines. The cabling can beused with devices needing power, dispensing fluid, dispensing gases,imaging, illumination, heating or cooling, etc. For example, the cablingoff the present disclosure can be used for a power drill to both powerthe drill and apply lubrication to cool the drill during operation.
